[U-Boot-Users] [PATCH][CFT] bring ARM memory layout in line with the documented behaviour
by Anders Larsen 07 Dec '03

07 Dec '03

Hi, here's a fairly lengthy patch against 0.4.8 that brings the memory layout of all supported ARM CPUs in line with the documentation. This has the positive side-effect of allowing U-Boot to actually run on PXA CPUs (the stock PXA implementation didn't set the start-address of the malloc pool at all!) The memory layout now more or less conforms to the standard as defined in the README (the absolute addresses are board-specific, of course). Since the stack and malloc-heap are now located below the U-Boot code, the TEXT_BASE of the supported ARM boards can be increased accordingly (for most (but not all) boards, the patch already does this). Memory layout example based on my PXA255 (TEXT_BASE = 0xA07E0000): 0xA079FF74 Monitor Stack (growing downwards) 0xA079FF80 Board Info Data and permanent copy of Global Data 0xA07A0000 Malloc Arena 0xA07E0000 RAM copy of Monitor Code ... optional: Frame Buffer 0xA07FFFFF [End of RAM] Since I only have access to PXA-based HW, I was only able to verify that U-Boot still *builds* for all supported ARMs; I have to rely on your help to see if it also *runs* correctly. CHANGELOG: Bring ARM memory layout in line with the documentation. Wolfgang: Please don't apply this patch until we have some feedback from the ARM maintainers. Robert: When/if this patch is eventually applied, you can probably push most of your PXA -ptx stuff without having it break things. Cheers Anders

[U-Boot-Users] Fix for MII utils
by Steven Scholz 06 Dec '03

06 Dec '03

Hi there, the attached patch addresses two MII related issues: a) mii info <addr> ignored <addr> and always showed info for 32 PHYs b) The "Trick" mentioned in miiphy_info(): " * Trick: we are reading two 16 registers into a 32 bit variable * so we do a 16 read into the high order bits of the variable (big * endian, you know), shift it down 16 bits, and the read the rest." does obviously not work on little endian machines. * Patch by Steven Scholz, 20 Oct 2003 - "mii info <addr>" now only shows the info for PHY "addr" as the help message already suggests - Endian fix for miiphy_info() Thanks, Steven

[U-Boot-Users] U-Boot hang
by Leon KUKOVEC 13 Nov '03

13 Nov '03

Hi everybody, I'm in the process of writting PCMCIA support for WEPEP250 (boards/wepep250). Everything seems to be going smooth except one thing: When I add a debug function and then execute U-Boot command "pinit on" or "ide reset" U-boot hangs on me. I sometimes get "data abort", sometimes "invalid instruction" and sometimes nothing. Is there any limits with regards to U-Boot's size and by me putting too much inside U-boot's .text section and hitting some marker/border ? The situation: ident_cpy() function used in ide_ident() copies firmware, version, ident string from iop structure to dev_desc structure. Since CompactFlash firmware string and model number string are in big endian byte order I wanted to write ident_swap_cpy, but as I wrote the function, re-compiled U-boot, downloaded it and issued "ide reset" I got a hang. I also tried to put just two printf's inside ident_copy() - a hang again. ident_swap_cpy() worked fine when I compiled and ran it in my examples/ide.c file. Thanks, -- Best Regards, Leon.

[U-Boot-Users] Help with u-boot 0.4.0 and IBM ASH board
by Wetterlind, Eric 03 Nov '03

03 Nov '03

Good afternoon... I have an IBM ASH (NPe405h) board that I am trying to get U-Boot 0.4.0 running on. Ultimately, I'll port this over to our custom board that is very similar to the ASH, but I figured it would be better to start on a known platform. I downloaded the new 0.4.0 U-Boot and ran these two commands (after modifying the Makefile to run 'ppc_405-' instead of 'ppc_8xx'): make ASH405_config make all It flew through compile and link to produce the nice u-boot.srec. I put that in my tftpboot directory, telnet'd over to the abatron 2000, erased ASH flash and programmed this new image in there. The result is an immediate SystemError LED illumination. I then switched from Flash to SRAM (one of the dips on the ASH board) and reloaded. Running from SRAM produces a program exception and jump to 0x700 almost right off the bat. I am running out of ideas on how to get U-boot and my ash board to cooperate. Has anyone else that has tried this had the same problems? Regards, Eric (eric.wetterlind(a)goodrich.com)

[U-Boot-Users] Motorola PPC827x

Yuli, I have a PQ2FADS_VR ( ppc8275 ) board from motorola which has a 66000000 Hz clock. Is it worthwhile to insert this anomaly to the u-boot code? I have done changes in MPC8260ADS.h file in order to make it run for me.

Matias> Can you explain me where the code for PPC8270 resides in the Matias> file structure? First of all, download the latest version from CVS (0.4.7 or CVS HEAD). Differences between 8260 and 8270 do not justify creating a separate CPU directory. In fact, all the differences result in some 10-20 lines of code, so look at cpu/mpc8260. Use `grep' to find HiP7 and you'll see the changes I made to support 8270/75/80. The same is true for PQ2FADS. I ported U-Boot to this board but since it's very similar to older MPC8260ADS I modified existing port to support all Motorola evaluation boards (MPC8260ADS/MPC8266ADS/PQ2FADS). Some differences are handled by #ifdefs. Cloning an existing port and changing ten lines to support new board as it's done in many cases creates maintenance nightmare. So the right place to look is board/mpc8260ads. BTW, I think it's mentioned in README.

[U-Boot-Users] Passing clocks to Linux (ARM)?
by Steven Scholz 31 Oct '03

31 Oct '03

Hi, Looking at the kernel source for AT91RM9200 cpus shows that the clocks for processor and bus are hardcoded. So for instance baudrate generator is programmed with some hardcoded value. I know that MPC8xx passes the clock values (and much more) from U-Boot to the Kernel. Has someone done that for ARM cpus? Is there a plan to extend bd_t structure for ARM as it is for PPC?

Hi Jacob, I found out the hard way by debugging and reading the source (the all important hint was a comment in board/wepep250/wepep250.c). BTW, it was quite an "interesting" task, since I did it on a freshly developed board (with hardware bugs, as it turned out!)... Cheers Anders

RE: [U-Boot-Users] omap5910
by Woodruff, Richard 30 Oct '03

The 5910 for all practically purposes is the 1510. I have seen a doc somewhere, not sure if I captured it or not. Basically, the difference is the way the parts are tested and sorted. The 1510 parts are speed rated, and you can get up to a 168MHx part. The 5910 parts are not and its only guaranteed up to 150MHz, but its likely many will run at 168. The 1510 also "claims" support for some functionality which the 5910 will not admit to having. The issue there is support and validation. 5910 parts will not be validated for everything a 1510 will be. I use a mix of both types of chips on development boards. I use their u-boot images interchangeably....I have set my timings back to 150MHz as the thing I've been working on will get parts stamped as 5910 not 1510.

There are a few processors which actually can "boot" from NAND. The OMAP161x is one such processor. It has hardware NAND support for ECC and fetching this along with some microcode in an internal mask ROM (on chip) can load up and execute code contained in Nand for boot. http://siliconvalley.internet.com/news/print.php/2224021 There is also a couple "integrated" chips which also allow booting from a "mainly" a nand device, like disk on chip and SuperNAND. http://www.m-sys.com/Content/Products/mobileDocPlusDiagram.asp As for what the SMDK2410 board is capable of, I have no idea.

My SMSC manual says about the BYTE COUNTER: "... alway even ...", Hmm , this code will put in even and odd length arguments.

Thanks for your reply Wolfgang, > > Try what happens when you "#define CONFIG_NET_MULTI" in your board > config file. The primary interface can be selected using the > "ethprime" environment variable. Here is a quick snippet of the config file :- /* * select ethernet configuration */ #undef CONFIG_ETHER_ON_SCC /* define if ethernet on SCC */ #define CONFIG_ETHER_ON_FCC /* define if ethernet on FCC */ #undef CONFIG_ETHER_NONE /* define if ethernet on neither */ #define CONFIG_NET_MULTI #define CONFIG_ETHER_ON_FCC1 #define CONFIG_ETHER_ON_FCC2 #define CFG_CMXFCR_MASK1 (CMXFCR_FC1|CMXFCR_RF1CS_MSK|CMXFCR_TF1CS_MSK) #define CFG_CMXFCR_VALUE1 (CMXFCR_RF1CS_CLK10|CMXFCR_TF1CS_CLK9) #define CFG_CMXFCR_MASK2 (CMXFCR_FC2|CMXFCR_RF2CS_MSK|CMXFCR_TF2CS_MSK) #define CFG_CMXFCR_VALUE2 (CMXFCR_RF2CS_CLK14|CMXFCR_TF2CS_CLK13) To be honest this is all I had to change, the addition of the ethprime env variable certainly helps as well, I'm not sure that I understand the intention of the code though. I was expecting the interfaces to be available similtaneously such that I could switch between them, perhaps this is not the case. I'll illustrate by using an example :- U-Boot 0.4.0 (Oct 27 2003 - 12:28:40) MPC8260 Reset Status: Software Watchdog, External Soft, External Hard MPC8260 Clock Configuration - Bus-to-Core Mult 4x, VCO Div 2, 60x Bus Freq 25-75 , Core Freq 100-300 - dfbrg 1, corecnf 0x1a, busdf 5, cpmdf 1, plldf 0, pllmf 2 - vco_out 396000000, scc_clk 99000000, brg_clk 24750000 - cpu_clk 264000000, cpm_clk 198000000, bus_clk 66000000 CPU: MPC8260 (Rev 14, Mask B.1 4K25A) at 264 MHz Board: Arca Technologies 82xx, Revision 0.0 I2C: ready DRAM: 128 MB FLASH: 8 MB In: serial Out: serial Err: serial Net: FCC1 ETHERNET, FCC2 ETHERNET [PRIME] BEDBUG:ready Hit any key to stop autoboot: 0 /******Ping using FCC2*******/ => ping 192.168.0.121 host 192.168.0.121 is alive /******Now disconnect FCC2*******/ /******Ping using FCC1*******/ => ping 192.168.0.121 ping failed; host 192.168.0.121 is not alive => If I switch the ethprime variable to FCC1 then reboot FCC1 works but FCC2 doesn't.

Hi Stephan, I'm glad to hear other Nios users are discovering u-boot :-) U-Boot and Nios is a great combination! > But now, I can't setup my network environment in expected way. > The u-boot environment vars "ethaddr", "iptable", "netmask", and > "serverip" are correct in flash, but bdinfo shows me the default > values (compiled in) -- Why ? Looks like I screwed up the call sequence in lib_nios/board.c ... the code is calling getenv("ethaddr") prior to env_init() -- must have been a late night ;-) The fields that depend on an initialized environment should be initialized _after_ calling the routines in init_sequence ... which includes env_init(). Try moving bi_ip_addr and bi_enetaddr below the init_sequence loop. I'm out-of-office so I can't work on a patch for a few days. If the changes work, please submit a patch to Wolfgang -- or we can work together off-line. Regards, --Scott

[U-Boot-Users] U-boot automatic selection of redundant ethernet interfaces?
by Mark Doherty 27 Oct '03

27 Oct '03

Hello u-boot-users, First a bit of background, I am using a custom processor board (similar to the ep8260) which has u-boot-0.4.0 running very nicely on it. The board has two ethernet interfaces which provide functionality like network address translation etc. Both interfaces are configured correctly, I know this as I have been using fcc2 and have only recently enabled fcc1 which is now the main port for the system. Now that both interfaces are configured I find that I can only use fcc1 for activities such as tftp etc. I have configured different eth addresses for both ports but I can't seem to get the system to use fcc2 rather than fcc1.The README does state that "u-boot is capable of automatic selection of an interface when needed", but I've not had much luck finding more information. Any takers? Regards Mark Doherty.

[U-Boot-Users] U-Boot for AT91RM9200DK
by Steven Scholz 27 Oct '03

27 Oct '03

Hi Rick et al., as I mentioned before U-Boot is running on our AT91RM9200 based board. I went down the path ATMEL was suggesting. They use this memory map on their eval board AT91RM9200DK: 24k Boot Image 32KB free 8KB Environment 64KB gzipped U-Boot image The "Boot image" is a small (11k) piece of code which initialises clocks, flash, SDRAM and serial port. Then it decompresses the "gzipped U-Boot image" into SDRAM and jumps to it. The reason for that seems to be: > We chose, to put a compressed boot due to memory mapping constraints. > We need to keep a sector for environment variables the 8Kbyte-size sector is > enough. They probably overlooked that you could embedded the environment into U-Boot. By using a correct u-boot.lds linker file one can reserve an 8Kbyte-size sector in the middle of U-Boot. So instead one could use this memory map: 56KB U-Boot 8KB Environment 64KB U-Boot using the same 128KB of flash. Since the CPU was setup by the bootloader there's no init and relocation code for the AT91RM9200 in U-Boot (yet). So I spend a day, "wrote" some init and relocation code and now U-Boot is starting directly from flash and relocates itself to RAM. No Preboot needed. Nor gzipped image of U-Boot. I would like to change the official U-Boot code for the AT91RM9200 and AT91RM9200DK so that it can be used without the need of another bootloader. This way it would be a lot easier for people to port U-Boot to their hardware. What do you think? Anyone interessted? I'd love to hear suggestion, where to put specific parts of the init code. Other ARM cpus use a board specific memsetup.S file. For an AT91RM9200 we have to setup more than just the SDRAM. Should we put all the init code into cpu/at91rm9200/{start.S} and use CONFIG_ and CFG_? Or should every AT91 based board copy the same code again and again into thier own subdirectory? Looking forward to your ideas! Thanks.

[U-Boot-Users] NIOS port at Stratix DevKit: distinctions between bdi and env
by Stephan Linz 27 Oct '03

27 Oct '03

Hi Scott and all other NIOS people, today I've successfully brought up and running the U-Boot NIOS port on a Stratix Development Kit (DK-1S10). Thanks to Scott -- was (is) a great work. The preconfigured Cyclone Edition was running and startup without critical problems, because as far as I know the Stratix edition is 100% equal to Cyclone except the FPGA. But now, I can't setup my network environment in expected way. The u-boot environment vars "ethaddr", "iptable", "netmask", and "serverip" are correct in flash, but bdinfo shows me the default values (compiled in) -- Why ? (logfile see attachment) Has anybody similar problems on Cyclone, or is it a Stratix problem (may be an useless question) ? Where can I found the setup flow from saved environment to bdi structure inside the u-boot source code? I want to check up the settings step by step. Ah: I'm using u-boot cvs snaphot date 20031024. Thanks, and best regards -- Mit freundlichen Gruessen Stephan Linz ====================================================================== Stephan Linz Softwareentwicklung MAZeT GmbH Email: mailto:linz@mazet.de Göschwitzer Str. 32 Tel. : (3641) 2809-55 D-07745 Jena Fax : (3641) 2809-12 Besuchen Sie bitte unsere Web-Seiten: http://www.MAZeT.de ======================================================================

[U-Boot-Users] U-Boot 0.4.0 on MBX with MPC821?
by cyborg＠embyte.net 26 Oct '03

26 Oct '03

Hello there, I'm trying to get U-Boot running on a Motorola MBX821-001 board. But up to now i couldn't manage it. After downloading U-Boot and flashing it (according to a ml thread of ppcboot-users: http://www.geocrawler.com/archives/3/4205/2001/12/0/7301427/ ) the MBX Board doesn't do anything but output wired characters on serial console. I've read the docs/README.MBX but it doesen't help. Has anyone successfully got U-Boot (or PPCboot) running on a MPC821 (or better on MBX821-001)?? Any hints or suggestions? Thanks in advance. Costel Mincea.

[U-Boot-Users] RESET on Lite5200
by Pascal FIFRE 25 Oct '03

25 Oct '03

I've used a Lite5200 (Version 2 : 64MB SDRAM, 16 MB FLASH) and I try to use U-Boot on It. I worked for now with a WireTAP JTAG debugger. I've flashed the latest code found in CVS tree and compile it with ppc_8xx. When I Reset (hard or soft reset) the cpu, the U-Boot doesn't work at all (I didn't see anything on the console). But when I use the debugger to reset the CPU and start the code in FLASH, U-boot works fine. The board has the default RESET configuration (Boot High, etc.). In the same way, when I flash the MOTOROLA DBBUG monitor on the board and RESET, it works. Can you help me ? Thanks

[U-Boot-Users] U-Boot and PPC
by Srikanth Sherman 23 Oct '03

23 Oct '03

Hello, I just found this list, so please bear with me if my questions are basic. I'd like to use the 440GX (or 440GP) so I got the ELDK and U-Boot 0.4. The ELDK doesn't specifically say that it supports the 440 series, do you know if anyone has been successfuly in building 440 binaries using ELDK? Also, I've never used U-Boot before, but I'm *assuming* that once I get U-Boot running on my board, I can just load up the application built with ELDK (assuming of course the it can build 440 compatible binaries) and it should work? Am I completely missing something here? Intially, I just want to get a simple "hello world" program working (ie, not attempting to boot Linux yet) Thanks very much for your time! Sri

[U-Boot-Users] Multi-file problem
by Rick Bronson 23 Oct '03

23 Oct '03

Hi, I found a problem with Mutli-file use of mkimage (using "-T multi") and fixed in my old u-boot-0.4.0 but my fix seemed to filter through too many files when I tried to do it (more correctly) on the cvs tree. Here's the problem (using 21-Oct-03 cvs files): When this address in cmd_bootm.c:1122 inside print_image_hdr() (is caculated: ulong *len_ptr = (ulong *)((ulong)hdr + sizeof(image_header_t)); it points to memory that wasn't copied back on cmd_bootm.c:174: memmove (&header, (char *)addr, sizeof(image_header_t)); because len_ptr points to the address header[1] and the memmove only moved header[0]. So I changed line 140 to: image_header_t header[2]; /* enough room for multi-image's size bytes too */ and all occurances of memmove (&header... from: memmove (&header, (char *)addr, sizeof(image_header_t)); to: memmove (&header, (char *)addr, sizeof(header)); But cmd_autoscript.c,common_util.c, armlinux.c uses &header and I'm not sure if this is the right fix. Maybe someone who knows this stuff can give me some direction. Thanks much. Rick

[U-Boot-Users] ICACHE and ARM ???
by Steven Scholz 23 Oct '03

23 Oct '03

Hi there, my new board using Atmel's AT91RM9200 is booting now straight up to the bash! But I noticed that the cache is _not_ enabled while U-Boot is running. That makes tftp und bootm very slow indeed. Now, enabling and disabling icache by accessing CP15, Reg 1 using a BDI2000 works fine. The speed up is remarkable. But the icache command does not work as I woud ecpect: MulitIO> icache p15/c1 is = c000007c Instruction Cache is OFF MulitIO> icache on icache_enable(145) p15/c1 is = c000007c write c000107c to p15/c1 p15/c1 is = 0000617c p15/c1 is = 0000617c Instruction Cache is OFF Hmm. So instead of just setting Bit 12 three other bits are set. Is someone using icache on ARM systems?

RE: [U-Boot-Users] Problem with LAN91C113
by Scott McNutt 21 Oct '03

21 Oct '03

Rick, I had the exact same problem when using LAN91C111 on the Nios DK-1C20 board (same status & incorrect length). You may need to define CONFIG_SMC_USE_32_BIT. If your bus interface to the chip is 32-bits, a full 32-bit read might be occuring when the data register is read. This throws away the second 16-bit word of the packet buffer (which is the packet length) -- so you end up skipping every other set of 2-bytes after reading the incorrect length.

[U-Boot-Users] Successful Port to PrPMC800
by Mark.Lightfoot＠sita.aero 21 Oct '03

21 Oct '03

Hello, I've successfully ported U-Boot to the Motorola PrPMC800. Support for FLASH, PCI, IDE and networking have bee successfully enabled. It has been in use now for several weeks in a stable form. I do have one lingering problem of not being able to turn on the L1 and L2 data caches. Doing so apparently causes the system to hang. Unfortunately I don't have a BDI2000 setup for this board to better debug the problem. I used just a good ol' console and plenty of printf statements to do the port. I can't give a specific time for when I will have the port submitted for a future release of U-Boot. But I will do it. I'd like to fix my cache problem first and I have to finish the rest of the project for which U-Boot is just one part. And that may be awhile. Regards, Mark.

[U-Boot-Users] How to optimize bit bang interface?
by Steven Scholz 21 Oct '03

21 Oct '03

Hi there, I am trying to configure an Altera FPGA using the so called "passive serial interface". Basicly it follows the scheme "clk low, data out, clock high". For testing I wrote the loop ts = get_timer (0); while (1) { if (get_timer (ts) > 10 * CFG_HZ) break; /* Deassert the clock */ (*fn->clk) (FALSE, TRUE, cookie); /* Assert the clock */ (*fn->clk) (TRUE, TRUE, cookie); }; fn->clk() is the function that the common FPGA code uses: int inline fpga_clk_fn(int assert_clk, int flush, int cookie) { if (assert_clk) *AT91C_PIOB_SODR = FPGA_DCLK; else *AT91C_PIOB_CODR = FPGA_DCLK; return assert_clk; } I noticed that this is awfully slow. I get arounf 50kHz using an AT91RM9200 running at 51MHz (core @ 171MHz). Could someone give me a hint how to optimize stuff like this for speed?

When u-boot runs up, I try to ping my host from u-boot,but the sniffer on my host cannot catch any hardware packet,but my host sends ARP REPLY packet to my board. and the sended packet is captured by sniffer.Unfortunitly,board does'nt seem to have received right packet.I've enabled ET_DEBUG,It prints: RCV: STATUS 42 LENGTH 8. AND LEDA & LEDB both lights! What is the reason? Can you give me some ideas? Thanks a lot! Ricky
